Trying to change livery on default Boeing 737

It's more simple :[fltsim.2] and [fltsim.5] have the same title Airbus A321 paint 5 so FSX says:There are multiple objects with the same title !Hope this helps :( (and by the way, you can copy Ctrl + C the text in aircraft.cfg and paste it in your message, it's more convenient to read) Pierre LFBE
